' NEEDLE-SHAPING freon] To all whom it may concern:

' Be it known that I, CHESTER LE ROY a citizen of the United States,- residin the county of Berks'and State of Pennsylvania,

Shaping Tools, of which the following is a i 1 specification.

1 This invention hasfreference to knitting machine needles, and in particular to that kind of needles which are'provided friction groove, depressiodor the like at some part intermediate-the ends of the neeimproper friction,

but ordinarily near the bearded or dle,

hooked part ofthe same for the purpose of retaining the meshes during and'immedi-ato the bumping of the machine whensuch knitting material, the formation of deficient needles are mounted upona circu lar or other kind of knitt ng mach ne; and

my invention is also intended to avoid other deficiencies in the making of the' knitted 1 fabric due to needles having improper fric tion, and to avoid the subsequent waste of sive number of holes inthe fabric, and the excessive repairs to the machines provided with such deficient needles. 'My invention has for one of its objects to avoid all these difficulties by providing means whereby the depression or friction groove or bend in the needles is always produced at the same distance from the hooked or similarly shaped end, and friction grooves and depressions of absolutely unifoimshape may be obtained at all times. Other objects and advantages of my invention will appear from the specification, claims and annexed drawing.

In the drawing which represents by way of example a preferred form of embodiment of my invention V Figure 1 is a side view with a portion of the lever which forms a part of my'invention, broken away. a a Figure 2 is atop plarrview of part of the device.

The particularconstructlon and configuration of the sides off f the projection and of the socket, however, 5

are not essential and may be changed to suit;

the convenience of the user. Aniadj'usting screw. lOwith setting nut .may be provided' at some suitable point ofjthe base 5,

of which it is fitted into the machine, 'as for of a circular instance into the cylinder It is evident that the particular construe tion of the needle itself is not material for my invention, and it'is to be understood that my invention is susceptible of various changes and modifications to suit the particular. conditions of usage to which the invention is to be applied.

In view of the absolute unitormityof the friction groove produced by my invention,

V longitudinal groove and transverse depresr sion, a lever-pivoted to the base and having a projection to fit in the depression, an adjustable stop carried by said base to form an abutment for one end of the needle, and

means for regulating the throw of the lever and the entry of theprojection'into the dedles, the combination of a base'having a longitudinal groove intersected by a depression, a stop forming an abutment 'for one end of the needle and adjustable with reference to the groove, a lever pivoted to the plate, a projection on the lever and adapted to enter the depression, and means for movement of the projection.

3. In a device for producing grooved needles, the combinationof a. base having a groove through the length of one edge and a transverse inclined sided socket, a stopdisposed adjacent to the groove a lever with a handle pivoted at oneend of the base, an adjusting screw at the other end of the base to limit the movement of thelever, and :1 projection having beveled sides carried by the lever between the pivot and the adjust ing screw andadapted to fit in the socket. to In testimony whereof I affix my signature.
